[0003] Due to the nature of the cosmetic effect, these cosmetics are required to hide uneven color such as spots and freckles existing on the skin when applied to the skin. Performance such as water repellency for preventing sensation and perspiration is also a problem. Conventionally, pigments with high hiding power, i.e., pigments with a high refractive index and pigments with high coloring power, such as titanium dioxide, red iron oxide, yellow iron oxide, and organic pigments, are used as coloring pigments in order to meet the demand for hiding color unevenness. And
Covering power has been increased, and a method has been adopted to make it difficult to see uneven color such as spots and freckles existing on the skin. However, pigments having a high hiding power as described above, that is, cosmetics containing many pigments having a high refractive power and pigments having a high coloring power show a thick cosmetic feeling when applied to the skin,
It has the disadvantage of becoming opaque and losing the natural skin feel.

[0004] On the other hand, conventionally, in order to impart a sense of transparency and bare skin to the makeup skin, a pigment having a small refractive index such as talc, kaolin, mica, mica, or the like has been blended into a cosmetic as an extender pigment. In addition, these extender pigments have been added to cosmetics in a large amount because they have superior usability such as spreading and sticking compared to the coloring pigments described above. However, when a large amount of such extender pigments are blended, they tend to give a glimpse to the appearance or give an unnatural luster when applied to the skin, so the surface of these extender pigments is coated with an inorganic silicate compound. (JP-A-60-228406), coating with an acrylic resin (JP-A-61-69708), etc., and blending the resulting pigment with cosmetics.
Attempts have been made to obtain clarity, bare skin and a natural finish. However, when a cosmetic containing the above-mentioned extender, an inorganic silicate compound-coated extender, an acrylic resin-coated extender, or the like is applied to the skin, it can have a transparent feeling and a bare skin feeling, but it is refracted itself. Since the pigment has a low ratio, the covering power is insufficient, and it has a drawback that the original function of the cosmetic, which hides the color unevenness such as spots and freckles existing on the skin, cannot be sufficiently exhibited.

[0005] In addition, when the cosmetic is applied to the skin, the performance such as elongation and smoothness on the skin is also a problem, and the powder is coated with an N-mono long-chain acyl basic amino acid for the purpose of improving feel and adhesion. (Japanese Patent Application Laid-Open No. 61-10503) has been proposed. However, as described above, pigments having a high hiding power conventionally used, i.e., pigments having a large refractive index and pigments having a high coloring power and extender pigments, inorganic silicate compound-coated pigments, acrylic resin-coated pigments, and the like are transparent. It has a drawback that it cannot satisfy both of imparting a feeling and a bare skin feeling and a cover of uneven color such as spots and freckles existing on the skin.

[0010] Such barium sulfate powder is produced by reacting a barium salt solution with a sulfate solution. The barium salt used here is soluble in a solvent such as water or alcohol, and examples thereof include barium chloride, barium nitrate, barium acetate, and barium hydroxide.
The purity is preferably 1000 ppm or less of metal ions other than barium so as not to impair the transparency characteristic of the cosmetic of the present invention. Sulfate means sulfate and sulfuric acid which are soluble in a solvent such as water and alcohol, and examples of the sulfate include sodium sulfate and ammonium sulfate. It is preferable to use a sulfate solution containing no.

The barium ion concentration of the barium salt solution and the sulfate ion concentration of the sulfate solution need to be 0.001 to 0.05 mole / l before the reaction. If these concentrations are less than 0.001 mole / l, the plate-like structure of the crystal is broken and becomes close to a columnar shape, so that the feeling of use is deteriorated and the yield as barium sulfate is lowered, which is not industrially preferable. On the other hand, if it exceeds 0.05 mole / l, the plate-like structure of the crystal is broken down into fine particles, so that the feeling of use is deteriorated, the light scattering effect is large, and the transparency is poor. In the reaction, the barium salt solution and the sulfate solution are mixed in a molar ratio of 1:10 to 5: 1. During the reaction, the pH is adjusted with hydrochloric acid, sulfuric acid and nitric acid as necessary so that the pH is 1.0 to 5.0, and the reaction temperature is 50 to 100 ° C, preferably 60 to 95 ° C.
When the pH and the reaction temperature are out of these ranges, the plate-like structure of the crystal is broken, and the feeling of use and transparency are deteriorated.

The barium sulfate powder obtained as described above has a scatter transmittance of 70% or more and a total transmittance of 8% when a thin film having a powder concentration of 20% by weight and a thickness of 25 μm is formed.
It has an optical property of 5% or more. Powders having such optical properties have high total transmittance, so that reflected scattered light is small.On the other hand, powders having high scattered transmittance have large transmitted scattered light. The transmitted light has the effect of being scattered and making the base blurred and difficult to see. Such an effect does not exist in the conventional pigment, and is hereinafter referred to as “sharpness suppressing effect”.

As a method of treating the barium sulfate powder with an N-mono long chain aliphatic acyl basic amino acid, any of a dry method and a wet method can be used. The dry method is simple and effective. The fine powder of N-mono long chain aliphatic acyl basic amino acid is mixed with barium sulfate powder with stirring, or the N-mono long chain aliphatic acyl basic amino acid is mixed with sulfuric acid. By mixing and then pulverizing the barium powder, the surface of the barium sulfate powder can be easily treated. Since the wet method hardly dissolves N-mono long-chain aliphatic acyl basic amino acids in water near neutrality and ordinary oil, calcium chloride is used as a solubilizing agent for N-mono long-chain aliphatic acyl basic amino acids. Is dissolved in an organic solvent, and then the barium sulfate powder is brought into contact with the powder, washed with water to remove calcium chloride, and dried to treat the surface of the barium sulfate powder. Alternatively, after dissolving the N-mono long-chain aliphatic acyl basic amino acid in acidic or alkaline water or aqueous solvent and contacting the barium sulfate powder, neutralize the solution to near neutrality and apply it to the surface of the barium sulfate powder. The same surface treatment can be performed by depositing and attaching an N-mono long-chain aliphatic acyl basic amino acid, removing salts produced by neutralization by washing with water, and drying (Japanese Patent Application Laid-Open No. 61-7202).

Test Example 1 The surface-treated powders obtained in Production Examples 1 and 2 were evaluated for water repellency and feel. (Method of evaluating water repellency) About 0.05 g of each powder was floated on 15 ml of water in a beaker for 30 ml, and the beaker was shaken to observe the dispersibility of the powder in water. The evaluation was based on the following criteria. 0: The powder was immediately dispersed in water. 1: When the beaker was shaken, the powder was almost completely dispersed in water within 30 seconds. 2: When the beaker was shaken, the water became cloudy and white after 1 minute, but floating powder was also observed. 3: When the beaker was shaken, the water became cloudy and white after one minute, but there were many floating powders. 4: One minute after the beaker was shaken, water did not become cloudy and no dispersed powder was observed. Even when the beaker was shaken for 5: 1 minutes or more, no powder dispersed in water was observed. (Feeling Evaluation Method) Five special panelists evaluated the feeling of the powder on the basis of the following five grades from 1 to 5 based on the smoothness, squeakiness, and roughness of the powder, and the average value was shown. In addition, plate-like barium sulfate H having an average particle size of 5 μm (produced by Sakai Chemical Industry Co., Ltd .: aspect ratio = 5, ratio of square of perimeter of plate-like surface to area of orthographic surface = 9: 1) The feel of the untreated powder was set to a standard value of 3.0. 1: Poor touch such as smoothness 2: Poor touch such as smoothness 3: Normal (equivalent to plate-like barium sulfate H) 4: Good touch such as smoothness 5: Good touch such as smoothness Table 1 shows the results.
